HEATING DEVICE FOR STOVES, 80C.

SPECIFICATION forming part of Letters Fatent No. 599,419, dated February 22, 1898. Application filed August 10, 1897. Serial No. 64:7,678. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL B. GOFF, a citizen of the United States, residing in the city and county of Camden, State of New Jersey, have invented a new and useful Improvement in Heating Devices for Stoves, Steam-Boilers, Furnaces, etc. ,which improvement is fully set forth in the following specification and accompanying drawings. I

My invention relates to heating devices for stoves, steam-boilers, furnaces, 850.; and itconsists of a novel manner of feeding and comnlingling the fluid combustible, air, and water employed in the proper proportions, provision being also made for withdrawing the products of combustion and returning the same to the fire-chamber to be consumed therein.

It also consists of a novel construction of commingling-chamber and its adjuncts, all the parts being readily assembled and disconnected according to requirements.

It further consists of novel details of construction, all as will be hereinafter fully set forth, and particularly pointed out in the claims.

Figure 1 represents a vertical sectional View of a heating device for a stove, &c., embodying my invention. Fig. 2 represents a section on line so at, Fig. 1. Fig. 3 represents a perspective View of a pan or receptacle supported above the fire-chamber, the same being provided with annular flues in the walls thereof. Fig. 4. represents a section on line y y, Fig. 3. Fig. 5 represents a perspective view, partly in section, of a portion of the upwardly-extending flue seen in Figs. 3 and at. Fig. 6 represents a perspective view of the commin gling-chamber employed, in which the fluid combustible, air, and vaporized water are received and commingled. Fig. 7 represents a perspective View of the fire-chamber in detached position.

Similar letters of reference indicate corre sponding parts in the figures.

Referring to the drawings, A designates a stove, the same consisting of a base B, which has the upwardly-extending outer walls 0 and the upright inner walls D, upon the upper edge of which is supported the rotary firechamber E, the latter consisting of the base portion F, which is perforated or apertured to serve as a grate and having the upwardlyextending walls G.

H designates a depending journal which extends from the bars F and is seated within the walls D.

J designates a receptacle or comminglingchamber and burner for the fluid combustible, said receptacle being in the present instance of the shape of a hollow cross, which is supported upon the bars F, the sides K of said cross having openings L therein for the escape of the fluid combustible, as will be explained. The top M of the receptacle J is in the pres ent instance removable and provided with the movable plate N, having the openings N, into which discharge the pipes P, Q, and R, which lead from the reservoirs S T U, respectively, said reservoirs being adapted for the reception of a fluid hydrocarbon combustible, water, and compressed air.

V designates a branch pipe leading from the pipe P to a point below the grate F. The said branch pipe serves to convey liquid hydrocarbon to a point beneath the grate.

W designates a pipe leading from the receptacle J to a thermometer or similar temperature-indicating device X, whereby the temperature of the contents of the receptacle J can always be ascertained.

Y designates lugs projecting from the top M of the receptacle J, upon which is supported the pan or water-holding receptacle Z, the latter having the base A and the upwardly-extending walls B, within which are formed the upright annular inclined flues or passages O, which are open at their bottoms and closed at their tops and sides, as will be understood from Figs. 1, 3, and 4, said pas sages discharging into the flues D, which eX- tend upwardly at either side of the pan Z.

E designates a flue into which the flues D discharge, the products of combustion or a portion thereof being finally conducted into the receptacle J through the flue F, while said products are also permitted to escape through the outlet G at the upper ends of said flues.

H and J designate lids which are superimposed above each other, thereby forming the oven K therebetween, said lids being recessed to permit the passage of the flues D.

The operation is as follows: In the space in the fire-chamber not occupied by the commin gling-receptacle and burner is placed hard or similar fuel. The fire is started in the usual manner and its combustion may be aided by allowing the liquid hydrocarbon to escape from the pipe V beneath the grate and igniting the same. After the combustion of the hard fuel has progressed sufficiently the fiow of liquid hydrocarbon from the pipe V can be checked. The products of combustion generated by the burning of the hard fuel in the fire-chamber heat the commingling-receptacle and burner J and also the pipes leading to the latter. The water and liquid hydrocarbon are thereby vaporized and the air heated. In the said receptacle and burner the heated air and vaporized water and hydrocarbon are mixed and pass through the openings L into the fire-chamber, where the mixture is consumed. After the fire has been started it can be fed by introducing hard fuel or the mixture of air and vapors, or both together, into the fire-chamber. The prodnets of combustion are conducted away by means of the fiues'O and D, aportion thereof passing into the commingling -chamber J, while the remainder escape through the opening Gr. Access can be readily had to the interior by means of suitable doors, and the several flues, pipes, &c., can be provided with dampers, valves, 850., according to requirements.

The oven K can be used for baking and the pan Z can be used for boiling water, &c.

In the preferred embodiment of my invention I locate an inverted funnel or conicalshap'ed shell at the junction of the flues D, the lower edge G of said funnel serving to arrest anysaturated steam in said lines D, said steam being condensed and returned through the fiues E to the commingling-chamber. It will also be apparent that more or less condensation will take place at or near the funnel or shell G2 and that, if desired, I may employ extraneous condensing devices.

In the preferred embodiment of my invention the pan Z is provided with annular channels A which can be utilized for boiling water or other fluids, said channels being more clearly seen in Fig. 3, since the same are removed from Fig. l for the sake of clearness of illustration. The flues D are supported upon the feet D which are sustained upon the brackets B as will be understood from Fig. 1.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1.
